1 Scope
1.1 These requirements cover electrical energy storage assemblies such as battery packs and
combination battery pack-electrochemical capacitor assemblies and the subassembly/modules that make
up these assemblies for use in electric-powered vehicles as defined in this standard.
1.2 This standard evaluates the electrical energy storage assembly’s ability to safely withstand simulated
abuse conditions and prevents any exposure of persons to hazards as a result of the abuse. This standard
evaluates the electric energy storage assembly and modules based upon the manufacturer’s specified
charge and discharge parameters at specified temperatures. It does not evaluate the assembly’s
interaction with other control systems within the vehicle.
1.3 This standard does not evaluate the performance or reliability of these devices.
1.4 This standard does not include requirements for the evaluation of batteries for light electric vehicles
such as electrical assist bicycles, wheel chairs, electric scooters and similar devices as defined in the
Standard for Batteries for Use In Light Electric Vehicle (LEV) Applications, UL 2271 / CAN/ULC-S2271.
